Professional Wasp Nest Removal Methods
Our Wasp Nest Treatment Methods
We use professional methods tailored to nest location and size:
- Insecticide Powder Treatment: Professional-grade permethrin or bendiocarb dust applied directly into nest entrance. Wasps carry powder into nest, contaminating entire colony. Most effective method for cavity nests.
- Spray Treatment: Liquid insecticide for exposed nests in lofts, sheds, or trees. Fast-acting formula kills on contact. Used when direct nest access is possible.
- Long-Reach Equipment: Specialist poles and applicators for high nests (chimneys, roof peaks). Allows safe treatment from ground level without ladders.
- Full Protective Equipment: Professional bee suits, gloves, and veils worn for all treatments. Ensures technician safety when treating aggressive nests.
- Follow-Up Guarantee: If wasps return within treatment period, we re-treat at no extra charge. Rare but covered in our service guarantee.
What to Expect During Treatment
Professional wasp nest removal process:
- Before Treatment: Keep all windows and doors closed. Keep children and pets indoors. Do not disturb the nest. Point out nest location from safe distance.
- During Treatment: Technician suits up in full protective equipment. Locates and assesses nest. Applies insecticide powder or spray directly to nest entrance. Treatment takes 30-60 minutes.
- After Treatment: Most wasps die within 24 hours. Complete nest elimination within 48 hours. Do not approach nest for 24 hours. Leave nest in place - it becomes inactive.
- Physical Nest Removal: NOT recommended. Once treated, nest is harmless and will naturally deteriorate. Removal risks disturbing surviving wasps. New wasps don't reuse old nests.
Preventing Wasp Nests

- Early treatment prevents large nests forming
Food Source Management

Wasp Nest Removal Services Across Westminster
Common wasps (Vespula vulgaris) and German wasps are prevalent in this area, particularly during peak season from August to September. Wasp nests are frequently found in lofts, wall cavities, roof spaces, and garden sheds. Properties with accessible roof spaces and older buildings with gaps in brickwork experience higher nest establishment rates. Professional treatment is essential as colonies can contain thousands of wasps, posing significant sting risks to residents and requiring specialist removal equipment.
